To all whom it comem.'

Be it known t at L'FRANK E. Cno'rro, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Im rovements in Well-Washing Devices, of which the following is a specification.

This invention has to do with well washing devices.

.The object of the invention is to provide a washing device for Artesian wells without screens and in which an enlarged ocketis formed at the bottom of the well. particular feature of the invention is the prov1 sion of outwardly swn 'ng nozzles arranged to be swun outwardly y the pressure of the washing uid and automaticall retracted when the pressure is cut off. `nother object is vto provide a plurality of nozzles, whereby the washing will be more expedltiously and more evenly carried out.

A construction designed to carry-out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understood from a readin of the following specification and by re 'erence to the accompanying drawin in which an example of the invention is s own and wherein:

Figure 1 is an elevation of a device constructed in accordance with my invention, the nozzles being extended,

Fig. 2 is a vertical sectional view of the upper portion of the device, a

ig. 3 is a vertlcal sectional view ofthe lower" portion of the device, y

Fig. 4 is la cross-sectional detail on the line/1 4 of Fig. 2,

'-Fi 5 is a cross-sectional view taken on the 11ne 55 of Fig. 3, and

Fi 6 is a cross-sectional view taken on the line 6 6 of Fig. 2.

In the drawings the numeral 10 designates a tubular housing having a guide plug 11 screwed into its lower end. The upper end of the housing is internally screw threaded and is mounted on the lower end of a head 12 into the upper end of which the lower end of a barrel `13 is screwed. The upper end of the barrel is screwed into a reducing couplin 14 which is screwed onto the lower en of a sleeve 15. The upper end of the sleeve is secured into a second reducing coupling 16, which receives' Speoloation of Letters Patent.

the lower end of the string of pipe 17, through which the cleaning fluid is supplied.

The head has three depending ni ples 18, although the numbermay var ,to which hose coupllngs 19 are attached. tube or hose 20 is secured to each coupling 19 and has its lower end connected w1th:a nozzle 21 by a second coupling 22. Vert1ca1 open1ngs or slots 23 in the side ofV the housln extend from the head to a point ust be ow the nozzle Each nozzle has its ower end beveled and its bore directed therethrough so as to outwardly. The fluid from the barrel 13 passes through ports 12 in-the head. The nozzles 'and hose are swung outwardly through the slots 23, but all parts are nor mally confined within the. diameter of the housing, as is shown in Fig. 3.

An actuating rod 24 extends axially through the housing, head, barrel and sleeve. The head has a central upstanding nipple 25 through which the rod slides. The lower end of the rod is confined in a guide tube 26 .screwed 1nto the plug 11. v A cross-head 27 1s fastened on the rod by a pin 28 within the housing and is provided with recesses 29 extending inwardly from its outer ed e, as 1s best shown in Fig. 5. The lower portion of each nozzle 1s pivoted between the lower ends of a pair of links 30 having their upper endsplvoted to the sides of the recesses 29. It w1 l be seen thatv when the cross-head is short flexible expel the cleaning fluid .l

moved downward by the rod, the links will u l swlng the nozzles outwardly and at an inclination as is shown in Fig. 1.

Within the barrel 13 a flanged collar 31 is fastened on the rod 24. A. coiled spring 32 surrounds the rod and has its lower end engaging about the nipple 25; while its upper end supports the collar 31. A second coiled spring 33 has its lower endengaged about t e collar 31 and its upper end fastened around a boss 34 on the underside of a wing valve '35 'within the sleeve 15. The spring 33 is considerably longer and of greater tension than the spring 32. The valve 35 is free to slide on the rod.

In o erating the device it is lowered into the wel until the housing 10 is within the oil sand pocket. The cleaning Huid, preferably water, is pumped into the line of pi e 17 so as to exert a ressure on the v ve 35, whereby it is isplaced dowtn- 25 washed at a time and the lworlr is more yield the spring 33 will yield.

" 12 and hose 20 to the nozzles 21.

The sleeve 15 is osuch length that the lower end of the valve will not pass below the'same until the nozzles are fully expanded and the s ring 33 under compression. When the spring 33 yields the lower end oli` the valve 35 will be carried down through the coupling 1li and into the upper end, but never far enough to withdraw its upper end from the sleeve. When the valve enters the coupling 14 the fluid will pass around sa1d valve and down through they barrel 13, ports When the nozzles are extended their beveled ends will alsy ' theo direct the jets of cleaning fluid 'against the sides of the pocket land cleanse the same. By employing three nozzles a greater area 1s evenly done than where only a single nozzle isused. The pipe 17 may be rotated so that the entire circumference of the pocketwill be washed, after which the housing is raised to wash at a higher level. When the fluid is cut off the springs' expand and returnthe parts to their normal pos1tion.

Various changes may be. made 1n the d1- mensions and construction and modifications may be made without departing from the spirit of the invention.

What I claim, is:

1. In a well cleaning device,.a housing having anv opening, a nozzle within the housing arranged to swing 'outwardly through the opening thereof, tubular connections for supplying lluid to the nozzle, a valve in one ofthe connections controlling .the supply of fluid, and means actuated' by the essure of the fluid 'for causing the nozzlii to be swung outward prior to the operation of the va ve to supply fluid to the said nozzle.

2. In a well cleaning device, a housing having an opening, a nozzle within the -housing arranged tol swing outwardly through ing thereof, tubular connections for supp ying fluid to the nozzle, a valve in one of the connections controlling the supply of fluid, and means actuated by the pressure of .the fluid for causing the nozzle to .be swung l `outward priorto the operation of the valve to supply lluid to the said nozzle, said means acting to retract the nozzle when the pressure of the fluid is relieved.

3. In a well cleaning device, a housing having-an opening, a nozzle pivoted within the housing, means for swinging the nozzle outwardly through the opening of' the housing, tubular connections for supplying a fluid under pressure to the nozzle, a valve in one of the connections controlling the supply of' lluid,and means actuated by the pressure of the fluid for operating the noz- \zle swinging means prior to the operation oi' the valve to supply fluid to the nozzle.

il.. In a well cleaning device, a pivotcd Jnozzle, means for swinging the nozzle outwardly, tubular connections for supplying fluid under pressure to the nozzle, means for controlling the passage of fluid through the connections to the nozzle, and means arctuated lby the pressure of the fluid for operating the nozzle swinging means prior to the operation of the controlling means to permit ,the passage of the fluid to the nozzle.'

5. In a well cleaning device, a pivotcd nozzle, means for swinging the nozzle outwardly, tubular connections for supplying fluid under pressure to the nozzle, means for controlling the passage of fluid through the connections to the nozzle, means actuated bythe the noz e swinging means prior tothe operation of the controlling means to permit 'the passage of the fluid to the nozzle, and means for restoring the parts to their normal position when the pressure of the fluid is relieved.

6. In a well cleaning device, a housing having vertical o enings, tubular connections attached to t ie housing, nozzles pivoted in the housing and connected with the tubular connections a sliding rod mounted in the housing and connections, swinging elements connected with the rod and the nozzles for swinging the nozzles outwardly through the o enin s of housing, a resilient support for t e rod, and a valve sustained on the rod for controlling the su )ply of a fluid under pressure to the nozz es, said valve acting to force the rod downward against the tension of the resilient support and operate the nozzle swinging elements prior to the passage of the fluid to the nozzles.

In testimony whereof I ailix m si ature.
